The correct Answer is:
To find the sum of the fractions \( \frac{5}{12} + \frac{7}{16} \), we will follow these steps: ### Step 1: Find the LCM of the denominators The denominators are 12 and 16. We will find the least common multiple (LCM) of these two numbers. - **Prime factorization of 12**: \[ 12 = 2^2 \times 3 \] - **Prime factorization of 16**: \[ 16 = 2^4 \] To find the LCM, we take the highest power of each prime factor: - For 2, the highest power is \( 2^4 \). - For 3, the highest power is \( 3^1 \). Thus, the LCM is: \[ LCM = 2^4 \times 3^1 = 16 \times 3 = 48 \] ### Step 2: Convert each fraction to have the same denominator Now we will convert both fractions to have the common denominator of 48. - For \( \frac{5}{12} \): \[ \frac{5}{12} = \frac{5 \times 4}{12 \times 4} = \frac{20}{48} \] - For \( \frac{7}{16} \): \[ \frac{7}{16} = \frac{7 \times 3}{16 \times 3} = \frac{21}{48} \] ### Step 3: Add the fractions Now that both fractions have the same denominator, we can add them: \[ \frac{20}{48} + \frac{21}{48} = \frac{20 + 21}{48} = \frac{41}{48} \] ### Final Answer The sum of \( \frac{5}{12} + \frac{7}{16} \) is: \[ \frac{41}{48} \] ---
